Players also have additional abilities, including a grenade launcher attachment, night-vision goggles, and the ability to call in airstrikes. Weapons from fallen foes can be picked up to replace weapons in a player's arsenal.
The player gains access to these over the course of the game, but may only carry up to two weapons in addition to grenades. The game's move to modern warfare introduces new weapons and technology to the Call of Duty franchise, including the M4A1 carbine, the M203 grenade launcher, the AN/PEQ-2 Target Pointer for use in conjunction with night vision goggles, the MP5SD submachine gun, and the FGM-148 Javelin portable anti-tank guided missile. Call of Duty 4 Modern Warfare is a first-person shooter similar to previous games in the Call of Duty series but set in the present-day instead of World War II.
